Patented Dec. 29, 1931 NETED STATES PATENT OFFICE OLIVER CHARLES LANGFORD AN D RONALD STANLEY LANGFORD, OF MOSELEY, BIRMINGHAM, ENGLAND BOX R CARTON FOR CONTAINING FRAGILE ARTICLES AND ITS MANUFACTURE Application filed November 20, 1930, Serial No Our invention relates to boxes or cartons for containing fragile articles, and their manufacture, and has for its object to provide such a device affording certain facilities for manufacture and package, which is adapted to hold the articles in a particularly efficient manner against fracture.

According to the present invention we provide a box or carton for containing fragile articles, comprising a rectangular bpx-like structure adapted to be closed at each extremity, and an integral diagonally disposed loeating trough or nest of V or equivalent formation at one extremity, constituted by a tongue integral with two of the walls of the structure, which tongue is provided with a crease in extension of that constituting the corner of the structure and certain oblique creases.

In order that this invention may be clearly understood and readily carried into practice, reference may be had to the appended explanatory sheet of drawings, upon which Figure 1 illustrates a blank from which a box or carton according to the present invention is adapted to be constructed.

Figure 2 illustrates the blank shown in Figure l (enlarged) brought into a box formation.

Figure 8 illustrates in perspective a further step wherein the integral tongue is in troduced into the lower part of the box to constitute the trough or nest.

Figure l is an inverted plan View particularly illustrating said trough or nest.

In a convenient embodiment of the present invention the box or carton is constructed of cardboard or like material and involves a one-piece blank comprising four rectangular sections a b c d and a small securing lip a adapted to locate the sections in box-like form (see particularly Figure 2). At the normally upper extremity of the box there is provided a closure flap a upon the wall a and a transversely disposed closure flap (Z on the wall (Z having a lip (Z adapted to be tucked into the box to locate both flaps a (Z in well known manner. In addition to this normally upper extremity of the box a further flap c is provided having a central aperture 0 with 496,922, and in Great Britain January 4, 1930.

radial slits c and parallel creases c in such a manner that this said apertured flap is normally sunk, say, some half-inch within the box (see particularly Figure 3). From this central aperture an electric lamp bulb c or the like (Figure 3) is adapted to be suspended.

The present invention however is more particularly concerned with the lower part of the box adapted for locating the bulbous part of the lamp 6. The lower part of the box is provided with flaps (Z c on adjacent walls as in the case of the upper part, said flaps being arranged to lie normally crosswise when the box is constituted, the flap d having a terminal part d adapted to be tucked into the box, but in addition to this, there is provided at the lower part of the box an integral oblong tongue a b of a width somewhat less than the overall width of the two walls a and b of the box (when the blank is considered in its flat state Figure 1), this said tongue a 6 having divergent edges a .71 connecting with the two walls of the box concerned. Centrally the tongue is creased as at a in continuance of the centre crease 03 occurring between the two walls a and b of the box, and further creases a are ar ranged in hexagonal formation. In fact, the creases a adjacent the walls a and b are advantageously duplicated as shown particularly in Figure 1. In the manufacture of the box the walls a F) 0 (Z are brought into the rectangular box-like formation and secured by the part a as shown in Figure 2, and the tongue a b seen protruding from the lower part of Figure 2 is seized by the hand and passed into the lower part of the box as shown in Figures 8 and 4 so that it constitutes a diagonally disposed V-shaped trough or nest, the oblique or hexagonal creases a permitting this trough or nest to seat itself coinfortably and securely within the walls of the box. If desired, one of the diagonal creases may be slit as at a to permit of the flange (Z on the closure flap (i being ultimately passed efliciently into the interior of the box.

In use, the lamp holder 6 is engaged with the aperture 0 in the flap 0 in the upper part of the box and the bulbous part of the lamp is passed into the interior until it is securely nested Within the trough or nest constituted by a b in the lower part of the box. The flaps a d at the upper part of the box are then closed those 0 (Z at the lower part having been previously closed or secured immediately upon the formation of the nest or trough a 6 We claim:

A container for fragile articles, comprising a rectangular box-like structure adapted to be closed at each extremity and a diagonally disposed locating trough or nest of V- or similar formation at one extremity constituted by a tongue integral with two Walls of said structure and of a lesser Width than the overall Width of the said tWo Walls, and having a crease in extension of that constituting one of the corners of said structure and further creases disposed in substantially hexagonal formation.
